Claims priority, application Switzerland May 13, 1953 3 Claims. (Cl.1108-28) This invention relates to a roofing timber-work with aprojecting roof which presents a ceiling formed with boards the faces ofwhich are horizontal.

In the accompanying drawings, two embodiments of such a timber-work areshown.

Fig. l is a perspective view of the first embodiment shown partly insection along a plane which is tangential to a lateral face of a rafter;

Fig. 2 is a bottom view of the second embodiment.

The timber-work represented in Fig. 1 comprises, at the top of a wall 2,a raising piece 3 supporting rafters 4 covered by the wainscotting 6 atthe under part of which is a board 7. This last board is secured to theupper edge of a platband which is analogous to an eaves'because it joinsthe lower ends of the rafters and because it supports one of the edgesof the gutter 13. This gutter extends along a projecting roof resultingfrom the fact that the rafters 4 extend to the outside of the wall 2.This projecting roof presents a ceiling formed by wooden boards 10 thefaces of which are horizontal as in known constructions but which aredisposed in such manner that they extend outwardly at right angles tothe wall instead of being parallel to the wall.

Boards 10 are separated from one another by spaces 11 having a widthcorresponding to the thickness of boards 10. At their ends adjacent tothe wall, boards 10 are secured to a strip 8, a part of which is shownout of the sectional plane, and suspension pieces 9 support strip 8 fromthe rafters 4. The ends of boards 10 adjacent the wall are nailed underthe strip 8 which is disposed horizontally against the wall. At apredetermined distance from their exterior ends, boards 10 are nailedunder the edge of the platband 5, these boards extending beyond thisplatband to an eaves 12 which is supported by their extremities. Eaves12 supports the exterior edge of the gutter 13 by the intermediary of acyma 14 made of sheetiron and having a band 15 for deflecting the water.The gutter 13 is then lodged in a compartment defined by platband 5,eaves 12 and the parts of the boards 10 which connect the platband withthe eaves.

The embodiment shown in Fig. 2 relates to buildings having walls orparts of walls which are incurved and concave or convex. The boards 101'which form the ceiling in these encurved parts have their axes ofsymmetry directed according to the radius of curvature. Their lateraledges are represented as being also directed according to the radii ofcurvature. more convergent than is the 'case when they converge to wardsthe curvature center, and in such a manner that the interstices may havea constant width along their length While the interstices 11a in Fig. 2are larger at one end than at the other.

In such dispositions, it is evident that the strip 8 follows a curve ata constant level or is made of fragments of rectilinear beams disposedaccording to a broken line approximately following this level curve.

But these edges could also be e Patent 0 2,849,966 Eatentetl Sept. 2,1958 ice The ends of the boards adjacent the walls could be directlyfixed in the wall or to a beam like strip 8 secured to the wall withoutthe intermediary of the suspension pieces 9.-

The boards of all the described forms such as 10 and ltli could beformed without their extension beyond the platband 5. Then, the eaves 12would be omitted and the platband 5 would be substituted by an ordinaryeaves provided with a groove like the groove 16 of the eaves 12 for thefitting of the ends of the boards and for their separation. The gutterwould then no longer be encased. The edges of the boards could beundulated instead of being straight.

In addition to an aesthetic advantage, the described ceiling of theprojecting roof presents the technical advantage of insuring theventilation of the latter, and which can, moreover, be entirely mountedbefore the roofer begins work.

What I claim and desire to secure by Letters Patent is:

1. A timber roof eave construction for walled buildings having a walland including rafters having their free ends extending outwardly fromthe building wall at a predetermined slope comprising, in combination, atimber member interconnecting the ends of said rafters and extendingtransversely thereto, a gutter having its inner side connected to saidtimber member, a plurality of board members extending longitudinallyoutwardly from the building wall under said rafters and under saidgutter and terminating in an outer timber member receiving the outerside of said gutter, whereby said gutter is underlain by saidlongitudinally extending board members, said board members being securedat least to one of said timber member and said rafters, a beam extendingtransversely of said board members and supported adjacent aid wall at apredetermined distance below said rafters, said board members beingsecured to said beam and thereby held in substantially horizontallyposition, and means securing said beam to said rafters.

2. A timber roof eave construction for walled buildings having a walland including rafters having their free ends extending outwardly fromthe building wall at a predetermined slope comprising, in combination, atimber member interconnecting the ends of said rafters and extendingtransversely thereto, a gutter having its inner side connected to saidtimber member, a plurality of laterally spaced-apart board membersextending longitudinally outwardly from the building wall under saidrafters and under said gutter and terminating in an outer timber memberreceiving the outer side of said gutter, whereby said gutter isunderlain by said longitudinally extending board members, said boardmembers being secured at least to one of said timber member and saidrafters, a beam extending transversely of said board members andsupported adjacent said wall at a predetermined distance below saidrafters, said board members being secured to said beam and thereby heldin substantially horizontal position, and means securing said beam tosaid rafters.

3. A timber roof eave construction having a corner portion whereinlongitudinal axes of symmetry of said board members lie on the radii ofa circle.
